Abstract

The utility model provides a foundation pit supporting wall with special-shaped reinforced concrete and cement soil separately arranged. The foundation pit supporting wall is characterized by comprising a cement soil water stop outer wall constructed through a double-shaft/triple-shaft cement mixing pile machine or TRD equipment, and a cast-in-situ special-shaped reinforced concrete soil block inner wall in a separately arranged mode. The special-shaped reinforced concrete soil block inner wall is formed by arranging tube-sinking cast-in-situ piles side by side, wherein cross sections of the tube-sinking cast-in-situ piles are of an I shape or T shape or rectangular shape, and the distance between the inner wall and the outer wall is 0.1-1m. Compared with the prior art, the foundation pit supporting wall has the remarkable advantages that the amount of consumed steel is reduced by 20-30 percent, the construction cost is reduced by 20-25 percent, and no mud pollution is caused. Compared with an original foundation pit supporting wall, the foundation pit supporting wall further has the advantages that the cement soil on a steel mold does not need to be shoveled off by workers, and labor intensity of the workers and construction cost are reduced.

Description

A kind of deformed bar concrete and cement-soil march-past pattern foundation pit supporting structure wall
Technical field
The utility model relates to building foundation pit supporting engineering field, relates in particular to a kind of deformed bar concrete and cement-soil march-past pattern foundation pit supporting structure wall.
Background technology
As everyone knows, the bending resistance square of foundation pit supporting pile is the same with the beam stress principle on building top, and square-section is better than circular cross-section cost performance, but does not see columned beam in the world, is but cylindric soldier pile everywhere.In discovery after cast-in-place deformed bar concrete pile core cement-soil diaphragm wall > > (ZL201120056477.3) for utility model < < pattern foundation pit supporting structure, this claim " in twin shaft or triaxial cement diaphragm wall, by spacing 0.8-3m, be provided with cast-in-place deformed bar concrete pile core, cement-earth underground continuous wall is that the cement mixing pile of diameter 0.5-1.5m intersects arranged side by side composition, reinforced concrete pile core cross section is I shape, or T font, or Back Word type, or rectangle, or oblate type ".In construction, there is larger problem, after being mainly cement mixing pile driving construction, shake in the cement-soil of the not initial set immediately punching block of heavy profile iron reinforced concrete pile core, is filling with concrete, finds that a large amount of cement-soils adhere on steel form while extricating oneself from a predicament and brace oneself up to action punching block, often pull out once, workman must shovel it with spades, thus, significantly increases labor strength, and pay great number reward, improved construction costs.
Utility model content
The purpose of this utility model is to provide deformed bar concrete and cement-soil march-past pattern foundation pit supporting structure wall, and than the cylindric bored pile scheme of existing design, the rolled steel dosage of use reduces 20-30%, and cost reduces 20-25%, mud-less pollution.Compare with former utility model, without workman, root out the cement-soil on punching block, reduce labor strength and construction cost.
The purpose of this utility model is achieved through the following technical solutions: a kind of deformed bar concrete and cement-soil march-past pattern foundation pit supporting structure wall, it is characterized in that, pattern foundation pit supporting structure wall is by the cement-soil water-stopping external wall of twin shaft or three axle cement mixing pile machines or TRD equipment construction, form with the native interior wall apportion of the concrete gear of cast-in-place deformed bar, deformed bar concrete inner wall is I-shaped by cross section or T font or the cast-in-place tube-sinking cast-in-situ pile of rectangle form side by side, interior exterior wall spacing 0.1-1m.
The utility model compared with prior art, has following remarkable advantage: the rolled steel dosage of use reduces 20-30%, and cost reduces 20-25%, mud-less pollution.Compare with former utility model, without workman, root out the cement-soil on punching block, reduce labor strength and construction cost.
Accompanying drawing explanation
Fig. 1 is an exemplary embodiments generalized section of the present utility model.
Fig. 2 is gear soil interior wall and the water-stopping external wall cross sectional representation of an exemplary embodiments of the present utility model.
In figure: 1 miscellaneous fill layer, 2 muds, the cement-soil exterior wall in 3 miscellaneous fills, 4 concrete Guan Liang, the cement-soil exterior wall of 5 muds, 6.T shape steel concrete interior wall, 7 foundation ditches, absolute altitude at the bottom of 8 foundation ditches, 9 main muscle, 10 stirrups.
The specific embodiment
An exemplary embodiments of the present utility model as shown in Figure 1, Figure 2, before building foundation pit excavation, it is rectangle punching block that vibrator sunk pile machine shakes into cross section in miscellaneous fill (1) and mud (2), and two protrusion blooms are established in punching block end, is of a size of T shape stake two corners.Punching block shakes and is sink to design elevation, puts into reinforcing cage then concrete perfusion in punching block, then the punching block of extricating oneself from a predicament and brace oneself up to action, what established punching block end two protrudes blooms and when upper pulling out, in soil, forms cavity, and concrete filling cavity forms the stake of T shape, complete a T shape pile driving construction, go round and begin again, complete all T shape pile driving constructions.By triaxial cement mixing pile machine, on foundation ditch building site, pressed again design drawing position construction cement-soil water-stopping external wall (3,5), complete the making construction of the utility model pattern foundation pit supporting structure wall, then by prior art earth excavation.

Claims (1)

1. a deformed bar concrete and cement-soil march-past pattern foundation pit supporting structure wall, it is characterized in that, pattern foundation pit supporting structure wall is by the cement-soil water-stopping external wall of twin shaft or three axle cement mixing pile machines or TRD equipment construction, form with the native interior wall apportion of the concrete gear of cast-in-place deformed bar, deformed bar concrete inner wall is I-shaped by cross section or T font or the cast-in-place tube-sinking cast-in-situ pile of rectangle form side by side, interior exterior wall spacing 0.1-1m.
